which is formed alined openings 25 formed integral thereon. The enlarged portion 23 is also provided with an opening 26, as shown in Fig. 41, for purposes to be hereinafter set forth. The yoke 2 1 embracesthe body 9 of the bolt 8, as shownin Fig. 2, at' which time a rivet or other securingmeans27 is passed through the openings 25 of the yoke '24: and

5 through the body '9, thuspivotally securing the inner'end of the operating arm 21 upon the swivel bolt 8. By the mounting of the arm in this manner it will beseen that the arm-maybeeither moved ina vertical plane by pivoting upon the rivet 27 or moved sidewise by the'swingi'ng orpivoting of the swivel bolt 8 upon the bracket 1. At this timethe offset lip 18 of the cam link 15 is'positioned so as to rest uponone side of the operatingfarm21, as shownin Fig. 2.

By having the lip 18 ofiset with respect to the enlarged portion of the cam link 15 it willbe seen that suiiicient space is provided between the greater portion of. the link and the arm for the reception ofthe weight 22. A pivot member, suchiior instanceas a'rivet 28 is passed through the opening 26 of the enlarged portion 23 and the opening. 190i the offset lip 18, thereby pivotally connecting th'ese elements together. A substantially inverted U-shaped locking clip 29 is carried by means of the rivet 30 in a fixed position upon the arm 21 and this clip 29 is provided with an outwardly. bent end 31 for assisting in directing the clip .over the camlink 1.5 whenthe'gateis in a closed position.

The pulley standard 6 is provided with a head piece 32 upon whioh is carried pulleys 33 although, of course, it is obvious that a double'pulley may be employed if so desired. The auxiliary pulley standards 34 are carried at considerablefdistances to either side of the gate and standards thereofand these auxiliary standards in turn have heads 35'carrying pulleys 36. The cables 37 ,are secured to the eye 38 formed uponthe outer end ofthe weight 22 and then pass up over the pulleys 33 carried by the head 32 of the pulley standard 6. The cables 37 then extend to pass over the pulleys 36 so as to hang down as shown in Fig. land carry weights 39. When this'deviceis in use and the gate is in a closed position it will be seen that'the operating arm 21 and the cam link 15 will extend in substantiallythe same horizontal planes, the downward movement of each element being limited by the fitting of the clip 29 over the link 15., At this time it will be seen that the gate 1 will be positively held in a closed position for any tend- ,zes

ency toward opening the. strain to be imparted directly trom the bolt 12 to the bolt -8'as the positioning of the arm 21 and the link 15 will constitute a'dead center between the two bolts, thus positively holding the gate closed. ,W hen it is desired to pass through'the gate-the cables27, may-bepulled over the pulleys 33 and 36, thus causing the weight 22 to be lifted and in turn the-outer end o'f'the operating arm 21 swung ,upwardly. Asi'this the gate l'will cause arm 21 is swung upwardly itwill draw upon the cam link 15 connected to the body 13101 is swung upwardly and-the link-.15 is pulled bythe arm 21 the distance between the pivot point-s ot the arm andthe linkwill be shortened considerably and necessarily the gate l will be opened. As-the gate opens the swivel-bolt Swill .turn sons-to allow the 3111121 to swing to one side; while the pivot rivet 27 will permit thearm to;

open position a quick but strong pull; or jerk should be imparted to oneof the cables which Y It is, of course, obvious that, if 't is ClBSlIGdtO retain the gate ina locked wardly until it reaches a substantiallyhorizontal plane extending across the top 'ofthe bracket 1. .TjllLlS,.1t will be seen that a subi-stanfiany a l'center with respect'to'the pivot connections of the arm and link will be maintained thus holding the gate in. an

open position and preventing its accidental closing. Of course,-thisfaction will swing the lip 18 of the cam link15 considerably over the rear portions of the bracket lto causethe shorteningot the cable- When it 1 is desired to close the gate either one of'the cables may be givena sharp jerk 'or pull,

thus swinging the weighted end of thearm .ardly so that the momentumof-the weight will swing the weight'forwardly 'and the continued pivotal movement ofthefa'rm 21 will push or shove uponthecamlink15 for; causing the link to push against lthe ib olt 12, thus moving the gate to a closed position.

As the gate moves to a .closed position" the clip' 29 will move over the cam link. 15ithus holding the operatingiarm '21 and the cam link 15 in alinement with .each other; pre-' senting the same dead center, with respect a locked closed position.

to the pivot points for holding the gate in I Y i connections of the cam link From the foregoing description it will be seen that a very-eflicient positively operating farm gate has been produced, wherein the and operating arm will cause the gate to either move to an open or closed position as the arm is being moved by the operating cables. Furthermore, it will be seen that after the movement of the extension of the link and arm in substantially horizontal planes will present substantially dead centers with respect to the pivot points for holding the link and arm against movement, which action will either cause the gate to be locked in an open or closed position. i 7

What is claimed is:-

1.- In a device of the combination of a gate, supporting said gate, ed upon said gate, said bolthaving a-body formed thereon, a cam link having parallel ears, said ears embracing said body, a bolt passing'through said ears andsaid body for pivotally mounting'said camlink upon said body,

class described, the means for pivotally plane as saidcam link, thus positively holding the gate in a locked position.

2. In a device of the class described, the combination of a gate, means for pivotally supporting said gate, a bracket comprising a substanpially inclined U-shaped body, a plate extending, from each end of said body Copies of this patent may be obtained for five cents each, by addressing th Washington, D.
